Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| J. R. Haynes 1973 | The genus Eggerelloides includes members of the Ataxophragmiidae with trochospiral initial part, at least in the microspheric generation, and triserial adult part. The aperture extends from the basal suture of the last chamber into the apertural face in a high arch or loop shape. There is a lip all round and the proximal border is inturned to make a connection with the previous foramen. The genus differs from Eggerella in its high, loop-shaped aperture and from Eggerellina in its trough-like internal tooth plate and multilocular initial part. The wall of E. scabrum with large quartz grains set in a matrix of much smaller grains is also distinctly different from the smooth, finely calcarenitic wall of the described Cretaceous species of Eggerellina. |
